America may indeed be obsessed with guns, but much of what passes as fact simply isn\'t true. The news media\'s focus on only tragic outcomes, while ignoring tragic events that were avoided, may be responsible for some misimpressions. Horrific events like the recent shooting in Arkansas receive massive news coverage, as they should, but the 2.5 million times each year that people use guns defensively are never discussed--including cases where public shootings are stopped before they happen.

Unfortunately, these misimpressions have real costs for people\'s safety. Many myths needlessly frighten people and prevent them from defending themselves most effectively.

Myth No. 1: When one is attacked, passive behavior is the safest approach.

The Department of Justice\'s National Crime Victimization Survey reports that the probability of serious injury from an attack is 2.5 times greater for women offering no resistance than for women resisting with a gun. Men also benefit from using a gun, but the benefits are smaller: offering no resistance is 1.4 times more likely to result in serious injury than resisting with a gun.

Myth No. 2: Friends or relatives are the most likely killers.

The myth is usually based on two claims: 1) 58 percent of murder victims are killed by either relatives or acquaintances and 2) anyone could be a murderer. With the broad definition of \"acquaintances\" used in the FBI\'s Uniform Crime Reports, most victims are indeed classified as knowing their killer. However, what is not made clear is that acquaintance murder primarily includes drug buyers killing drug pushers, cabdrivers killed by first-time customers, gang members killing other gang members, prostitutes killed by their clients, and so on.

Only one city, Chicago, reports a precise breakdown on the nature of acquaintance killings: between 1990 and 1995 just 17 percent of murder victims were either family members, friends, neighbors and/or roommates. Murderers also are not your average citizen. For example, about 90 percent of adult murderers have already had a criminal record as an adult. Murderers are overwhelmingly young males with low IQs and who have difficult times getting along with others. Furthermore, unfortunately, murder is disproportionately committed against blacks and by blacks.

Myth No. 3: The United States has such a high murder rate because Americans own so many guns.

There is no international evidence backing this up. The Swiss, New Zealanders and Finns all own guns as frequently as Americans, yet in 1995 Switzerland had a murder rate 40 percent lower than Germany\'s, and New Zealand had one lower than Australia\'s. Finland and Sweden have very different gun ownership rates, but very similar murder rates. Israel, with a higher gun ownership rate than the U.S., has a murder rate 40 percent below Canada\'s. When one studies all countries rather than just a select few as is usually done, there is absolutely no relationship between gun ownership and murder.

Myth No. 4: If law-abiding citizens are allowed to carry concealed handguns, people will end up shooting each other after traffic accidents as well as accidentally shooting police officers.

Millions of people currently hold concealed handgun permits, and some states have issued them for as long as 60 years. Yet, only one permit holder has ever been arrested for using a concealed handgun after a traffic accident and that case was ruled as self-defense. The type of person willing to go through the permitting process is extremely law-abiding. In Florida, almost 444,000 licenses were granted from 1987 to 1997, but only 84 people have lost their licenses for felonies involving firearms. Most violations that lead to permits being revoked involve accidentally carrying a gun into restricted areas, like airports or schools. In Virginia, not a single permit holder has committed a violent crime. Similarly encouraging results have been reported for Kentucky, Nevada, North Carolina, South Carolina, Texas and Tennessee (the only other states where information is available).

Myth No. 5: The family gun is more likely to kill you or someone you know than to kill in self-defense.

The studies yielding such numbers never actually inquired as to whose gun was used in the killing. Instead, if a household owned a gun and if a person in that household or someone they knew was shot to death while in the home, the gun in the household was blamed. In fact, virtually all the killings in these studies were committed by guns brought in by an intruder. No more than four percent of the gun deaths can be attributed to the homeowner\'s gun. The very fact that most people were killed by intruders also surely raises questions about why they owned guns in the first place and whether they had sufficient protection.

How many attacks have been deterred from ever occurring by the potential victims owning a gun? My own research finds that more concealed handguns, and increased gun ownership generally, unambiguously deter murders, robbery, and aggravated assaults. This is also in line with the well-known fact that criminals prefer attacking victims that they consider weak. These are only some of the myths about guns and crime that drive the public policy debate. We must not lose sight of the ultimate question: Will allowing law-abiding citizens to own guns save lives? The evidence strongly indicates that it does.
